The Harlequin Hydroclear 30 Person Sewage Treatment Plant is the market leader with pollutant removal level of 96.6%. Wastewater from toilets, showers, kitchens etc is fed directly into the treatment plant, and out the other end comes clarified effluent suitable to be discharged into a soakaway or stream. Market-leading performance, easy installation, virtually inaudible operation, low maintenance costs, reliable bio media system and durability are all qualities that make the product best suited for all off-mains sewage treatment requirements. 

As standard the Hydroclear HC30 comes as a Gravity Discharge System, if required this can be upgraded to a Pumped Discharge System.

Fitted as standard with a mains powered Air Blower Function Alarm, alerting you to a failure of this component.

Key Benefits of the Harlequin Hydroclear HC30

Virtually Inaudible – High performance diaphragm blowers are used and externally housed achieving a virtually silent operation.
Odourless – The system is hermetically sealed, coupled with a market leading treatment performance eliminates odour.
MBBR Technology – Moving Bed Biological Reactor (MBBR) systems are self-cleaning and unable to become blocked through channelling unlike most fixed film media systems.
Market leading performance – Producing an excellent 96.6% pollutant removal level, the final effluent can be directly discharged into a stream or soakaway.
Low Maintenance Costs – Chamber one capacity is as much as 66% larger than other plants, making desludging intervals up to three times longer saving the owner significant costs.
Power Failure Default – The system keeps performing as a septic tank in the event of a power failure.
