Different Process Options on offer:
 
Tecroveer developed its own range of mechanical equipment in conjunction with various well-proven activated sludge processes. Tecroveer offer a specific design approach and the client can ad or delete items according to his budget.
 
By combining these processes with Tecroveer patented technology we can offer a quality product at an affordable price.
 
 
Process Selection:
 
1.         Tec Type A (Extended Aeration)
 
Basic description
Consist either of a reactor circular with the clarifier in the middle or a Pasveer ditch with an adjacent single or double clarifier (determined by the slope of the terrain). Surge volume created on surface of reactor. Elevated Clarifier is normally a 60 deg Dortmund cone clarifier. Mixed liquor is pumped to clarifier with aerator pump and sludge return is done hydrostatically. (No sludge pumps are required.) If combined with adjacent sludge lagoons the WAS, Scum and Supernatant Return can be done with the hydraulic water level difference between Clarifier and the Reactor.
 
            Main Advantages:
  • Proven as one of the most reliable cost effective systems in the market today.
  • Total amount of mechanicals required is: Inlet screen, rag catcher, one Bridge Aerator Pump, SS Chlorine Pill basket and a drainer pump to empty the sludge lagoons once every year.
  • Easy to operate and maintain.
  • Can absorb high seasonal variations and shock loads.
  • Arguably one of the most odour free biological treatment units on the market.
 
            Effluent Quality Expected:
 
Will comply with the old General Standards of the water Act. Nitrogen levels requested in the new “ General Authorisations 1998” will only be periodically achieved.
 
            Application: Low Budget Basic Treatment Unit:
  • Used extensively in small remote communities with low level of skilled operators. (Service various Hospitals in Mapumalanga, KZN Midlands and Eastern Cape this is some of the most remote places in SA)
  • Application where a relative clean effluent is to be irrigated. For example at Golf Estates or holiday resorts. (Leopard Rock Hotel Zimbabwe)
  • Limited use since 1998 because of new legislation standards on effluent into a natural causeway.
  • Recommended size 50 kl/day to 1000 kl/day.
