Sewage Treatment and Recycling Challenge

Challenge for conventional STP

include:

• Centralized nature of treatment

• With increase in Sewage generation,

Centralized plant have Zero scope of

capacity expansion

• Difficulty to meet existing norms due to

every increasing complexity of Sewage

• Increasing issue of Sludge

Management and disposal

• High foot print of conventional

technology, limiting scale of new plant

• Limited water reuse scope with poor

output quality

Why Decentralized Sewage Treatment seems difficult ?

• Conventional Technologies lime Activated Sludge process

were designed for Centralized solution.

• ASP is very high of foot print, energy usage , solid waste

generation and skilled manpower

• Decentralized plant start from an individual level, to single

house, a building complex and for whole community

• Old technologies cannot be scaled up

• High foot print prevents their use in densely populated

urban centres which are hot spot of sewage pollution

• Options like MBBR and FAB need high investment and

high level of technical expertise to generate consistent

water quality of reuse.

• Modular, Mobile and Package plant are a very high on

Capex

BIOFLOCS compared to conventional treatment plants

BIOFLOCS Conventional like ASP, MBBR,

FAB etc.Higher concentration of MLSS gives Better

treatment in less space

Lower MLSS concentration leads to high foot print

of treatment plants

Residence time (HRT) of sewage in reactor is low

due to high concentration of bacteria

Reactor have high residence time due to low

concentration of bacterial mass, increasing the

plant foot print and civil cost

Bacterial removal is very good, nearly 100 % Bacterial removal is very poor

The plant takes less start-up time compared to

MBBR as the bacterial growth is suspended

Attached bacterial growth (as in MBBR, FAB,

SAAF) requires longer time and high level of

expertise for operation and stabilization

Sludge generation is less due to high biomass

concentration

High sludge generation

Removal of nutrients like Ammonia, Nitrate and

phosphate is good

Removal of nutrients like Ammonia, Nitrate and

phosphate is poor

Operating cost of plant is at PAR with a properly

functioning conventional technology plant

Operating cost of (sub 100 KL) plant is in the

range of Rs. 12 – Rs. 20 per KL depending on the

operating condition of plant

New STP norms – A Challenge to conventional technology

It would be difficult to

meet the new STP

norms using

conventional methods,

without making the

plants more BIGGER

BIOFLOCS – Membrane based Sewage Treatment solution

• BIOFLOCS process is based on use

of Submerged membrane for solid

liquid separation.

• It belongs to Membrane

Bioreactor (MBR) family

• Low Footprint and high quality water

treatment are hallmark of Membrane

based BIOFLOCS treatment

• Design of BIOFLOCS is done to

carter Sewage Treatment

requirement of single family to full

fledge community.

How BIOFLOCS – Membrane solution works ?

• Hollow Fiber based filtration is at the heart of BIOFLOCS

Bundle of hollow fibre (making sufficient filtration area) is submerged in the bioreactor

How BIOFLOCS – Membrane solution works ?

• In the Bioreactor, clean water gets collected in the hollow fibre cavity, leaving the biomass outside

How BIOFLOCS – Membrane solution works ?

• Backwash is regularly applied to prevent clogging (fouling) of hollow fibre membrane

BIOFLOCS Advantage in Sewage Treatment

• High MLSS (6,000 – 12,000 mg/L) => low HRT => small reactor volume => small plant footprint

area

• Biomass separation is independent of settling; separation is via microfiltration or ultrafiltration.

• Biomass is completely retained, effluent TSS (< 1 mg/L) and turbidity (< 1 NTU) is very low.

• Due to microfiltration or ultrafiltration, BIOFLOCS provides a perfect physical disinfection.

Removals:

o 5-6 log bacteria

o 2-3 log viruses

o Complete removal of pathogenic protozoa such as the chlorine-resistant

Cryptosporidium and Giardia.

• Automated operation, operator requirements are reduced

• Due to elevated SRTs: less susceptible to problems associated with nitrification and toxic organics,

less biomass yield => less sludge

• Due to high MLSS, high loadings allowed

• Better SRT control since no escape of TSS as occasionally observed from secondary clarifiers

• Can also remove nitrogen and phosphorus with the addition of anaerobic and anoxic zones

BIOFLOCS Advantage in Sewage Treatment

• Extremely low plant footprint

• Simple construction makes for easy repair and

replacement

• Custom design and low capital and cost makes

BIOFLCOS installation in most difficult location

possible

• There is reduced demand for post treatment

chlorination

• Low sludge production compared to conventional

treatment process

• Generation of treated water quality ideal for Flushing

and other non-potable applications.

• Plants can be underground, over ground,

basement based etc.
