BIO-CLEAR Packaged Treatment Plant

The Bio-Clear packaged sewage treatment system is designed or developmehotels, and rural communities that are reuired to treat wastewater to ldischarge"

The multi-stage treatment process includes screening, difused aeration, crecirculation, sludge digestion, #ltration, and disinection" Pre-engineered mosuch as difused air !lowers, aeration tanks, sludge holding tanks, clari#ers, andallow or the package plants to !e si$ed speci#cally or the customer%s applicatio

How it Works

&astewater enters the package plant #rst passing through a !ar screen or largethe euali$ation tank water is retained to create a homogenous mi(ture prior tentry into the aeration !asin, water is mi(ed with an active !iomass in a rolling place over the length and width o the cham!er" The cham!ers are #lleted on !ottom to enhance the rolling motion and eliminate any *dead $ones* in theeature also minimi$es the accumulation o scum and roth in the aeration tank"

+ter sucient contact time in the aeration cham!er, water ows into the clari#in the hopper-!ottom tank" Solids are recirculated through the system or withClean water ows through the clari#er into the clearwell where it is re-pressthrough the tertiary #lters and disinection systems"

Depending on the desired #nal water uality, a mine may also use other techn

Passie water treatment

Passive water treatment is usually com!ined with water monitoring (rogadvantage o natural physical, chemical, and !iological processes tha

contaminates without additional physical or chemical inputs" (amples o

include !acteria-controlled metal precipitation, contaminate uptake !y pla

through soil and sediments" +lthough passive water treatment has !een us

treat municipal wastewater and ur!an runof, its use in the mining indu

development, largely !ecause o the challenge o treating highly acidic watchallenges, low operation and maintenance costs continue to generate interes

treatment, especially or use ater mine closure"

Constr"cted wetlands are the most common orm o passive water technowetlands act as natural puri#cation systems which are capa!le o #ltering an

contaminates !eore they are transported into marine or reshwater environm

it is dicult to achieve ideal contaminate removal conditions, and passive

currently reuires ongoing maintenance and treatment"
