Distributor / authorized representative that deals with supply & delivery of sand filters to industrial enterprises of Russia

Engineering company ‘Intech GmbH’ LLC (ООО «Интех ГмбХ»), Russia, has been successfully working with a number of Russian industrial enterprises at the local market for more than 20 years. Since the company’s founding, it has acquired immense engineering experience, market reputation, and has realized more than a hundred large-scale projects at the industrial plants in Russia. Our company is continuously in search of new business partners, who consider Russian market investment-attractive and want to boost their sales in the region, as well as expand their field of activities and enter a new international level.

We are interested in cooperation with the manufacturers of sand filters, 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 sand filters. 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 sand filters, will submit a market overview for sand filters 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 sand filters 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 sand filters 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 sand filters 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 sand filters 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 sand filters. They will also provide necessary training and guidance for the customer’s personnel.

Sand filters. A brief overwiew

Sand filter scheme and principle of operation

Calculation of sand filters

The required number of filters is defined with the following formula:

NF = 0.5√(FF)

where FF is a total area of filters, m2.

Calculation of the total area of filter is carried out according to the formula:

Ff = Qw / (t·VR - n·qwash - n·tst·VR)

where Qw is a daily flow,
t is an operation time of treatment plant during one day (hours),
VR is a rated filtration rate (under normal operating conditions),
n is a number of filter washings,
qwash is a specific water flow, used for one filter washing,
tst is a facility standing time as a result of filter washing (measured in hours).

It is worth noting, that all the other filters must operate with accelerated speed during washing of one filtration facility. Velocity value must not exceed seven meters. When being in compliance with the heavy-speed mode, liquids filtration rate can be determined from the following formula:

Vf = Vw · (Nf)/(Nf - N)

where N is the number of filters being repaired or washed, and Nf is the total number of filters being in working state. The following formula is used to calculate one filter area:


In this formula, NF is the total number of all the filters (measured in pcs.)

Drawing of a pressure-type sand filter

In some cases, it is necessary to provide sand filters with a mechanical agitator for sand stirring-up to improve treatment quality. Mechanical agitators operate only during sand cleaning by backflow of washing water and they are switched off during filtration.

This formula is used to calculate water filtration rate:

w = 3600·c·d²·(h/l)·(0.7+0.03·t)

where w is a filtration rate (m/sec),
c is a correction factor which equals to 40, approximately,
d is the diameter of sand grains (m),
h is the pressure loss (m H2O),
l is the layer thickness (m)
t is a water temperature (°C).

Knowing the flow speed, it is possible to calculate the approximate flow rate of liquid. This means that it is possible to calculate the filter performance based on the sand layer porosity.
