ABS Group > Wastewater treatment

Clean water is essential to people and environments the world over. ABS plays a major role in returning clean water to its source by providing effective solutions for wastewater treatment. ABS treatment products and services focus on safety, reliability and efficiency of the wastewater treatment processes.

Critical demands
Wastewater treatment is demanding. Capital investments, operating costs, growing populations and environmental legislations are big concerns. Choosing the most cost-effective solution from one of many equipment suppliers is not easy. Maintaining and upgrading existing treatment systems is no small task either. The mission to protect a growing population and a limited resource, makes the choice of an experienced wastewater technology partner crucial.

The solution provider
Wastewater professionals worldwide are working with ABS solutions to remove organic pollutants, phosphates and nitrates, to protect surface and groundwater, to ensure safe coastal and bathing water qualities, and to process sludge for energy. Cost-effective solutions for new plants or refurbishments of existing installations are the strength of ABS. Our application know-how vouches for the optimal selection and combination of products and services for each unique application.

Maximized efficiency and minimized cost
The ABS service program covers all aspects of operation and maintenance of pumps, mixers, aerators and automated controls from initial pumping station design to proposals on complete treatment facility management – and everything in between. The program helps treatment plants to maximize operating efficiency and minimize costs.

PRODUCTS

ABS submersible sewage pump AFP

ABS submersible pumps from 1.7 - 1,300 hp for reliable and economic pumping of heavily polluted sewage in commercial, industrial and municipal applications. Water pressure-tight encapsulated flood-proof motors in standard or explosion-proof versions with option of jacket cooling system. Suitable for both wet and dry installation. Hydraulics with open or closed, single or multi-vane impellers suitable for handling of clear water, polluted water, sewage containing solids, faecal slurry and sludge.

ABS submersible mixed flow column Pump AFL

The ABS AFL series is a range of submersible mixed flow column pumps for direct installation in discharge pipes that save space and installation costs. They are intended for large flows and moderate heads for stormwater, land drainage and flood protection. The ABS
AFL can handle sewage from commercial, municipal and industrial sources as well as liquids containing solids and fibrous material.

ABS submersible sewage pump AFP-ME

The new AFP-ME is the core product range for sewage and wastewater applications, offering reliable sewage pumps from 9 - 110 kW (50 Hz) and 125 kW (60 Hz). The AFP-ME supplies blockage-free pumping and superior reliability, along with the highest motor efficiency in the submersible pump industry.

ABS dry installed sewage pump FR

The dry installed sewage pump FR is developed for economic pumping of heavily polluted sewage and wastewater in municipal and
industrial applications. The back-pull-out design utilizes standard electrical motors, making the pump service-friendly. Ample space
inside the impeller and volute makes the pumps less prone to clogging. A double seal arrangement makes dry running possible. The units are supplied with vortex impellers or with the Contrablock system for reduction of clogging.

ABS submersible recirculation pump RCP

The submersible recirculation pumps RCP are used for pumping and circulating activated sludge in wastewater treatment plants, especially for the denitrification/ nitrification process. The selfcleaning propeller is intended for lightly polluted sewage and activated sludge. The hydraulic efficiency is very high when pumping large flow and low heads. In contrast to conventional axial flow pumps, the ABS RCP recirculation pumps do not require expensive structures in the tank. The compact unit is lowered along a guide
tube and is easily connected to the pipeline by ABS automatic coupling system.

ABS submersible mixer RW

The ABS RW mixers have an integral motor and are suitable for agitating, blending, mixing, dissolving and suspension of solids in
municipal treatment plants, industry and agriculture. ABS offers highly efficient multipole and gear driven mixers with either standard or explosion proof motor enclosures. ABS application support includes literature and computer software for sizing and
design of each installation.

ABS flow booster SB

The ABS flow boosters SB are slow running submersible units with integral motors for gentle circulation and mixing of fluids in treatment plants and industrial applications. The ABS flow booster is complete
with monocast propeller blades and excellent self-cleaning properties, giving optimum operation with low energy input. The unit is connected
to a concrete pedestal by an innovative coupling system, which allows the unit to be raised and lowered for inspection even in filled tanks.

ABS Scaba agitator

The ABS Scaba agitators are of a robust, modular design and can be combined with various types of drive units, seals and impellers. The propeller makes the required process perform at the lowest possible
power input. Treatment of highly polluted water or other biodegradable masses with high organic pollutants can produce biogas and energy by
using ABS Scaba agitators within anaerobic digester. The ABS agitator is individually tailored for different types of wastewater and tanks. By using special software, the most reliable solution for any type of mixing problems can be accurately designed.

ABS High Speed Turbocompressor

The ABS turbocompressor HST provide pressurized air to the aeration system. The ABS HST
is an integrated turbocompressor based on a high speed motor driven by a frequency converter. No mechanical wearing parts or lubricants are used in the HST. This is made possible by electronically controlled magnetic bearing technology which levitates the integrated
rotor-impeller single-piece assembly. The optimized drive technology controls the machine’s rotational speed, thus achieving optimal operating efficiency and minimizing energy consumption. Full control of flow and pressure within the whole operating range is possible and is accessible both locally and remotely. The ABS turbocompressors HST are used in wastewater treatment plants and in industrial low pressure processes.

ABS submersible sewage pump AFP (K)

ABS submersible sewage pumps AFP (K) from 2 - 40 hp for reliable and economic pumping of heavily polluted sewage in commercial, industrial and municipal applications. Water pressure-tight encapsulated flood-proof motors in standard or explosion-proof versions insulated to Class H, with option of closed loop cooling system and seal cartridge. Suitable for both wet and dry installation. Wide range of impellers suitable for handling of clear water, polluted water, sewage containing solids, faecal slurry and trash.

ABS Submersible Mixer SB 1200 KA

The ABS submersible mixer SB 1200 KA combines all the specific requirements of those treatment processes where the biofilm is bound on the surface of plastic carriers. The low tip speed in combination with a special designed propeller, prevent any
negative effects on the carrier material during the mixing. The energy cost is reduced thanks to a unique drive unit design including a high efficient gear box.
