Equipment for the Waste Water Treatment

Design and manufacturing of Mechanical equipment for the Waste Water Treatment industry

Shosalowe is an Engineering Company that specialises in the design and manufacturing of mechanical equipment for the waste water treatment industry. Shosalowe mainly concentrates on the design and manufacturing of mechanical equipment for the sewage industry.Although we are able provide all the equipment for an entire sewage plant, we mainly specialise in the two sections that receive normally less attention compared to the BNR section, such inlet works screens and sludge handling by means of mechanical equipment such as Belt press equipment.The two areas, i.e. screening and sludge handling and dewatering are the two areas where waste is produced.

Screening | Front Rake Screens | De-gritting

The standard inlet works design comprises of screening using screens such as front rake screens. The screenings are normally transported by a screw or hydro conveyor to a screw press or a screw wash press.The next step after screening and screenings handling is the removal of grit and sand called de-gritting.De-gritting is normally performed by grit channels or Vortex de-gritter equipment.The grit and sand is normally removed by submersible pumps or air lift pumps.The grit and sand are then pumped to a classifier where the main portion of the grit and sand is removed mechanically. A classifier mainly consists of a settling hopper and a spiral screw conveyor.The grit and sand are settling in the settling zone whereafter the grit and sand are slowly removed by the action of the spiral screw conveyor.

Handling and dewatering of the different sludges

The second area of concentration is the handling and dewatering of the different sludges, such as anaerobic digested sludge and waste activated sludge.The two sludge streams, i.e. anaerobic digested sludge and waste activated sludge can be combined in one stream for dewatering or in separate streams for dewatering.To serve the ever demanding market and sewage treatment problems in South Africa, Shosalowe tied up with various European companies to provide the South African Waste Water Treatment market with a very wide range of proven technologies and equipment. Shosalowe formed the following partnerships with European companies as listed below:

  • Teknofanghi – Sludge Dewatering with The Monobelt
  • Biolak- Economic complete WWTW
  • Vandezande – Large Screw pumps

 

Another company, Wamechsi was also formed during the technology search exercise. Wamechsi is mostly involved with contract and installation of the Teknofanghi Monobelt. Shosalowe is mostly responsible for the design and manufacturing of inlet works equipment such as mechanical Front Rake screens and sludge treatment plants using the Teknofanghi Monobelt.The Teknofanghi Monobelt is used in many applications such as:

  • Large Sludge treatment plants, using 5 or more Teknofanghi Monobelt press systems
  • Containerised sludge treatment plants, using 1off Teknofanghi Monobelt press system complete with Polymer make-up units
  • Mobile sludge treatment plants, using 1off Teknofanghi Monobelt press system complete with Polymer make-up and dosing units
  • Automatic dredging plants, using 1off Teknofanghi Monobelt press system complete with pre-thickener , Polymer make-up and dosing units

 

Dam, pond or sludge lagoon Dredging | Dredging Systems

Shosalowe and Wamechsi also specialises in dam, pond or sludge lagoon dredging. Shosalowe have both small and super large dredging systems. The dredging systems can be supplied as manual or fully automatic operating systems. The dredging systems can dredge any size dam, pond or sludge lagoon. The dredging systems are able to operate over a wide range of depths, 1 – 4m. The dredging system can be connected to a Mobile sludge treatment plants, using 1 off Teknofanghi Monobelt press system complete with Polymer make-up and dosing units. The solids are removed by the dredger and transported to the mobile sludge treatment plant where the sludge is removed and the clean water, called filtrate is returned to the dam, pond or sludge lagoon.
