Triple-action system

Triplus ’ s triple-layer waste system with a ventilation branch is an ideal solution for high-rise buildings with a high factor of simultaneous use of the sanitary appliances .
The waste system guarantees excellent ventilation of the stack and branch connections on each floor , thus limiting pressure fluctuations within the system . This system also allows significant advantages in terms of cost savings , thanks to the possibility of creating one soil stack ( therefore , no separate ventilation pipes are required ) with one 110mm diameter , with more than double the discharge capacities of primary ventilation systems .

It ’ s all in the borehole

Pentax electrical submersible pumps are available in a Franklin or BT ( Tesla ) submersible electric motor . The pumps are suitable for both single-phase ( 230V ) and three-phase ( 400V ) electricity applications .
The pumps are suitable for water rising and distribution installations that require high pressure and flow rates . Water plants and systems for residential and industrial use are some examples of applications that are suitable for the submersible pump . They can be used for continuous or intermittent duty operations .
Some of the design features of the pump include a motor coupling flange and a discharge head made from stainless steel . The pump is able to operate in conditions of up to 30 ° sand content ( 150g / m 3 ).

Dealing with wastewater underground

The Bio-Mite from Calcamite has been engineered to treat domestic and industrial wastewater to a level that conforms to the national standards . The system configuration enables better oxygen transfer efficiency with plug flow conditions . Submerged fixed film growth in SAFF reactors sustain good microbial growth even in adverse conditions and also handles shock loads very well . Sludge production is low ; no sludge recirculations are required , and mean cell residence time is enhanced .
Air requirement is based only on the organic load . Mixing requirements are not called for , as this system is primarily an attached growth system . The media is a randomly packed polypropylene filter media and has wide application in biological treatment systems . The reactors are up-flow or down-flow fixed film type , based on either anaerobic or aerobic treatment processes .
