Dry well pumping stations offered by Ecol-Unicon are designed according to individual Client’s needs. There are two types of dry well pumping stations depending on the amount of wastewater inflow

• ETS dry well pumping station used mainly in facilities where wastewater inflow does not exceed 60 m³/h
• ESS dry well pumping station with two-channel suspended solids separator is used in facilities where wastewater inflow exceeds 60 m³/h

Ecol-Unicon dry well pumping stations have CE marking according to PN-EN 12050-1:2002.

Advantages

• the possibility of servicing the technological part of one of the two inflow circulations during the work of the dry well pumping station;
• total elimination of odours
• the body is made from stainless steel – no need for using additional anti corrosion coating
• fast and easy access for servicing to all technological components of the unit – the pumps, the separator, flexible flaps of the separator, check and cutoff fittings and the inflow pipeline divider;
• the possibility of using pumps from different producers, selected individually on the basis of the project design or according to the Client’s requirements;
• suspended solids separation and no physical contact between the pump’s rotor and the impurities, which prolongs its life and allows to use the pumps having lower flow passage and higher efficiency – economic operation.

TYPES:

ETS Compressor Station

The ETS Compressor Station has two single-channel solids separators,, which are located outside the retention module, at the pump discharge ports. This allows for quick inspection and access to its interior. Due to the design of the separator, the ETS pumping station is suitable for sewage inflow rates of up to 36 m3/h. The unit module is made of stainless steel.

ETS-PE Compressor Station (NEW)

The ETS PE sewage pumping station is a pumping station adapted for sewage inflow from 1 to 20m3/h. The ETS pumping station has two single-channel solids separators located directly at the discharge ports of pumps operating alternately, in the external part of the retention module. This solution makes it possible to quickly control the operation of the separator and the flexible straining flap, and to efficiently service the unit as well as all its modules. The module with retention tank is made of PEHD, tested for compliance with the PN-EN 12050 standard, the innovative construction of the body distinguishes this model in the market. It is worth mentioning that the retention module is integrated with the body, together they form one coherent device. The pump and additional installations, such as a ladder, flushing system or operating platform, are selected based on individual user requirements and project documentation. This approach makes it possible to comprehensively tailor the unit to the needs of a specific customer.

ESS Compressor Station

The ESS Compressor Station features two dual-channel solids separators equipped with flexible straining flaps. The separators are located inside the retention module at the pump discharge ports. When the inflow rate of wastewater to the compressor station exceeds 50 m3/h, a by-pass system is used, consisting of a bypass pipe, a pneumatic gate valve and a compressor. The ESS compressor station has a module made of stainless steel. Due to the design of the two-channel separator, it is suitable for very high sewage inflow rates, operating up to 250 m3/h.

ESS-PE Compressor Station 

The ESS-PE Compressor Station contains two dual-channel solids separators equipped with flexible straining flaps. The separators are located inside the retention module at the pump discharge ports. When the inflow rate of wastewater to the compressor station exceeds 50 m3/h, a by-pass system is used, consisting of a bypass pipe, a pneumatic gate valve and a compressor. The ESS-PE compressor station has a module made entirely (body, module and piping) of PEHD. Due to the design of the two-channel separator, it is suitable for very high sewage inflow rates, operating up to 200 m3/h.

The ESS-PE Stamping Plant has an innovative design, where the retention module together with the body, made of PEHD, are integrated (permanently connected), forming one coherent device. The compressor station has a plug&play design, which means that a complete device with installed equipment and hydraulic-mechanical fittings is delivered to the construction site.

Dry well pumping stations (ETS) just like pumping stations (EPS) are devices used for wastewater pumping. They are used on the areas with diverse landforms – where the population is scarce, in households and industrial facilities located far away from the disposal sites as well as in urban areas. The rising amount of suspended solids present in wastewater, which is the result of saving water, proves dry well pumping stations to be a more rational solution (Tab. 1). Separation of suspended solids used in dry well pumping stations increases the effectiveness and reliability of the whole device and allows to use pumps of higher pumping efficiency (rotors having lower free passage). Installing the pumps and the dry well pumping station module inside a dry chamber improves the conditions of operation and maintenance. Leak-tight retention chamber fitted with pipe chimney eliminates all odours.

The decision to choose a traditional pumping station (wet pumping station) and a dry well pumping station (dry well pumping station with impurities separation) or an intermediate option – dry pumping station (pumping station without impurities separation) – is taken together by the investor, the user and the designer.

Operation

ETS dry well pumping station is an automatic device that does not need constant supervision and frequent maintenance. The device should undergo thorough technical inspection on regular basis. Taking into consideration different composition of wastewater the frequency of technical inspections should be determined individually – at least once a year. The maintenance of pumps and electric devices should be done according to the producer’s documentation.

The first inspection should be done within six months following the startup of the device and later once a year with the normal workload. The failure to carry out regular inspections according to the producer’s recommendations will void the warranty.
