Sewage Treatment and Industrial Wastewater Treatment Summary – 100% Recycle and Reuse
The Flush ‘n CLLEEN™ treatment units convert sewage into potable water
and non-hazardous, garden-safe fertilizer.
The ElectroCoagulation of our EC-CLLEEN™ treatment converts heavy metals to their “Earth-friendly” oxide forms, and kills greater than 99.99% of E. Coli, Cryptosporidium, Coliform and all other forms of bacteria.
The coagulated particles are clarified, and the sludge recovered is non-hazardous, “garden-safe” fertilizer.
The effluent is then sent through the CLLEEN™ MSF unit, where at least 70% of the water is recovered as pure H2O (less than 5 ppm TDS).
IN MORE DETAIL
CLLEEN™ Water and Power™ has combined with ElectroCoagulation specialists to produce the most energy-efficient (versus RO) toilet-to-tap sewage treatment recycle system on the market.
Raw sewage is screened for non-dissolvables, as per current sewage treatment, then sent through the electrocoagulation unit whereby a small electrical charge and the use of sacrificial metal plates, kills 99.999% of bacteria, including fecal coliform and E. Coli, and convert any ionic metals in the water to their “Earth-friendly” oxide forms.
The EC system efficacy with regard to septage treatment has been verified by two independent third-party laboratories, The University of South Florida, and The Office of Naval Research (ONR).
The septage is then pumped to a vacuum clarifier, where the solids settle to form a non-hazardous US EPA “CLASS A” sludge, which does not need disposal in a hazardous landfill, or other special handling or carting. It can be land applied or sold as clean fill.
The clarifier effluent is pumped through the CLLEEN™ Multi-Stage Flash (MSF) distillation variant. The CLLEEN™ system is a breakthrough in distillation technology. First, the feedwater is heated by the condensate of the titanium plate heat exchanger (Stage 1). Next, the heated feedwater is pumped and distributed (via a proprietary system) into the heated flash chamber and pulses of compressed air are used to increase the separation of water molecules into vapor (Stage 2), whereby the vapor is drawn off by a vacuum pump and sent through a heat exchanger. The remaining water and TDS are collected at the bottom of the chamber as a concentrated brine.
For most water treatment processes, including seawater desalination, these two steps alone would suffice to make a more concentrated brine of at between 15-30% (versus 40-50% for RO) of water by volume, and the condensate is potable water of less than 5 ppm TDS.
However, septage or sewage treatment, because of the high concentrations of ammonia and ammonium ions in the water, need secondary treatment. The concentrated brine is sent back to the clarifier in a recycle stream to remove the TDS and roughly 20% of the ammonia.
The condensate is now pure H2O (less than 5 ppm TDS) and ammonia that has flashed with the vapor in the flash chamber. The condensate is pumped through a secondary CLLEEN™DA Deaerator whereby the ammonia is recovered as a gas and bubbled through the recovered clarifier sludge to make a nitrogen-rich fertilizer available for land application or resale. The condensate is purified of ammonia and is potable water of less than 5 ppm TDS.
Because the flash chamber heats the water to above 160degF, post unit disinfection is not necessary. However, since the water is likely to be stored in tanks or storage containers, a UV system is added to ensure proper disinfection.
