Distributor / authorized representative that deals with supply & delivery of grit classifiers (sand separators) to industrial enterprises of Russia

We are interested in cooperation with the manufacturers of grit classifiers (sand separators), who are looking for an official and reliable distributor to deal with supply & delivery of their equipment to the industrial plants in Russia.

The company’s top management and sales team are well acquainted with the Russian market, its mentality and laws; they also understand industrial specifics of the financial and economic activities of the Russian customers. All our sales managers have a large customer database, extensive experience of successful sales and well-established connections with the potential buyers of your grit classifiers (sand separators). This allows our managers to promptly set out the most promising directions for promotion and to ensure a rapid entry of the products into the promising Russian market. Our employees, who are fluent in English and German, are focused on working at the international market with the supplies of foreign equipment.

Our team of experienced engineers, who can handle the most serious technical problems, constantly keeps in touch with the Russian customers, holds meetings and delivers presentations regarding the latest achievements of our manufacturing partners. They point out the engineering challenges and actively communicate with all the departments at Russian plants. That is why the specifics of doing a business in the Russian Federation are well-known to us, and we also know the equipment of the local industrial plants and their up-to-date modernization needs.

Once we become your authorized representative in Russia, our marketing staff will carry out a market research in order to check the demand for grit classifiers (sand separators), will submit a market overview for grit classifiers (sand separators) that you offer and evaluate the needs for this type of equipment at local plants. Our specialists will also estimate the potential and capacity of this market at local industrial plants. Our IT-team will start developing a website for your products in Russian. Our experts will assess the conformity between your grit classifiers (sand separators) and customer needs as well as analyze the common reaction to the new goods in general. We will look into the categories of potential customers, and pick out the largest and the most promising plants.

Upon becoming your authorized agent on the territory of Russia, ‘Intech GmbH’ LLC (ООО «Интех ГмбХ»), will obtain certificates, if required, for a batch of the goods, for various types of grit classifiers (sand separators) in compliance with Russian standards. We can also arrange the inspection in order to obtain TR TS 010 and TR TS 012 Certificates. These certificates provides permission to operate your equipment at all industrial plants of the EAEU countries (Russia, Kazakhstan, Belarus, Armenia, Kyrgyzstan), including the hazardous industrial facilities. Our company is eager to assist in issuing Technical Passports for grit classifiers (sand separators) as per Russian and other EAEU countries’ requirements.

Our engineering company ‘Intech GmbH’ LLC (ООО «Интех ГмбХ»), collaborates with several Russian design institutes in various industrial segments, which allows us to conduct preliminary design as well as subsequent design works according to the standards, construction rules and regulations that are applicable in Russia and other CIS countries. It also enables us to include your grit classifiers (sand separators) into the future projects.

The Company has its own logistics department that can provide packing service, handling as well as the most efficient and cost effective mode of transportation of the goods (incl. over dimensional and overweight goods). The goods can be delivered on DAP or DDP-customer’s warehouse basis in full compliance with all the relevant regulations and requirements that are applicable on the Russian market.

Our company has its own certified specialists who will carry out installation supervision and commissioning of the delivered equipment, as well as further guarantee and post-guarantee maintenance of grit classifiers. They will also provide necessary training and guidance for the customer’s personnel.

Grit classifiers (sand separators). A brief overwiew

Grit classifiers (sand separators) are designed to separator mineral particles larger than 0.2-0.25 mm in wastewater. They are installed on sewage treatment plants with the capacity of 100 m³/day.

Grit classifiers (sand separators) have several variants of designs:

  • horizontal-flow (water flow moves in a straight line or in a circle);
  • vertical-flow (water moves from top to bottom);
  • tangential-flow (water is supplied tangentially);
  • aerated (water movement is enhanced by air supply).

The number of grit classifiers (sand separators) or their compartments should be no less than two. If sand removal is carried out mechanically, a stand-by sand separator is also installed.

Horizontal-flow grit classifiers (sand separators)

They are used if the water consumption is more than 10 thous. m³/day. Sand separator is a tank, having a length of 0.25-1 m, where the water stream flows at a rate of 0.15-0.3 m/s. Water should stay in the tank for at least 30 seconds. The rate of particles settling depends on their hydraulic size. Grit classifiers (sand separators) with a circular movement of water, having a rounded shape, are usually used for small volumes of up to 70 thous. m³ day.

Tangential-flow grit classifiers (sand separators)

They are not able to treat large amounts of water. It is recommended to use them at a water rate of no more than 50 thous. m³/day. Such grit classifiers (sand separators) have a rounded shape.

Aerated grit classifiers (sand separators)

Like the horizontal-flow ones, such grit classifiers (sand separators) are used if it is necessary to treat large volumes of water, ranging from 10 thous. m³/day. Such grit classifiers (sand separators) represent horizontally positioned tanks. When water enters the tank, the flow direction of the stream coincides with the direction of stream rotation in the sand separator. The submerged weir is used. Aerators are mounted at one of the walls along the entire length of the device. The pipes with 3-5 mm holes are used as aerators. Aerators are located at a distance of 45-60 mm from the bottom, and the tank for sand collection is mounted under the aerators. The bottom of aerator is inclined at 0.2-0.4 with respect to the chute, allowing the sand to move easily into it.

Vertical-flow grit classifiers (sand separators)

Use of them is highly inefficient, and they are used only in exceptional cases.

Calculation of sand separator (using horizontal-flow sand separator as an example)

It is necessary to define a number of values to calculate the horizontal-flow sand separator. First, clear area should be calculated:

F = q/(v*n)

where F is a clear area of the sand separator, m²;
q is a maximum flow rate, m³/s;
v is an average water velocity, m/s;
n is a number of compartments.

Next, the length of the sand separator is calculated:

L = k*v*h1/u0

where L is a length of the sand separator, m; k is a correction factor; h1 is the depth of the flow part of the sand separator, m; u0 is a speed of particle settling, m/s; v is an average water velocity, m/s.


Upon becoming the official distributer of grit classifiers (sand separators), our company ‘Intech GmbH’ LLC (ООО «Интех ГмбХ»), carries out the following: finds the buyers of your products on the market, conducts technical and commercial negotiations with the customers regarding the supplies of your equipment, concludes contracts. Should a bidding take place, we will collect and prepare all the documents required for the participation, conclude all the necessary contracts for the supply of your equipment, as well as register the goods (grit classifiers (sand separators)) and conduct customs clearance procedures. We will also register a certificate of transaction (Passport of Deal) required for all foreign trade contracts in the foreign currency control department of the authorized Russian bank so that currency transaction could be effected. If required, our company will implement an equipment spacing project in order to integrate your equipment into the existing or newly built production plant.

We are convinced that our company ‘Intech GmbH’ LLC (ООО «Интех ГмбХ»), will become your reliable, qualified and efficient partner & distributor in Russia.

We are always open for cooperation, so let’s move forward together!
