SEPTIC tank CM
Concrete SEPTIC tank CM is a domestic wastewater treatment for black and grey water. Septic CM is a cylindrical mono chamber concrete tank.
Septic tank is a wastewater pretreatment usually installed upstream to a public sewer discharge or to a small wastewater treatment as activated sludge plants, trickling filters, bio-disc, etc. Septic tanks are useful to remove coarse materials, fats and oils, sands or others matters that, if not stopped, can cause problem, as clogging or equipment breakages, on the forward treatment. Septic tank also homogenizes incoming flow, increasing the post treatment efficiency.
SEPTIC tank CM is made of a single prefabricated reinforced concrete tank.
Nominal capacity (CN) is the main dimensional parameter according to European standard EN 12566-1. It is provided with inlet and outlet baffles at least 30 cm below the water surface.
Grease and foams are stored on water surface, above outlet baffle level, while sludge is stored on the bottom of the tank. Stored matter must be periodically removed by cleaning and maintenance operation.
Concrete SEPTIC tank CM is a mono-bloc (single unit) reinforced concrete tank for underground and aboveground (available on request) installation.
Available for vehicle access (light or heavy), with concrete, stainless steel or cast iron manhole cover (available on request).
Three category available: B125, C250 or D400.
SEPTIC CM line is available from CN 2 up to 15; volume range from 2,700 up to 15,900 litres .
