ABOUT BIO-FLOCS TECHNOLOGIES Aim of BIO-FLOCS TECHNOLOGIES is to develop Low Cost but Advanced indigenous products for Sewage, Wastewater and Water Treatment and Recycling BIO-FLOCS TECHNOLOGIES is developing technologies targeted at:

Individual

Industrial

Commercial

Domestic

Community

RECICLAR Technologies is focusing on:

Membrane based Biological treatment like MBR, Bf-MBR and others

Electrochemical process like Electrocoagulation

Hybrid process like EC-MBR

Business Model adopted by Neo Crystal is Research, Development, Demonstration and Deployment using Distributor and Retailer network.




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 Lower MLSS concentration leads to high foot print

treatment in less space of treatment plants

Residence time (HRT) of sewage in reactor is low Reactor have high residence time due to low

due to high concentration of bacteria 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 Attached bacterial growth (as in MBBR, FAB,

MBBR as the bacterial growth is suspended SAAF) requires longer time and high level of

expertise for operation and stabilization

Sludge generation is less due to high biomass High sludge generation

concentration

Removal of nutrients like Ammonia, Nitrate and Removal of nutrients like Ammonia, Nitrate and

phosphate is good phosphate is poor

Operating cost of plant is at PAR with a properly Operating cost of (sub 100 KL) plant is in the

functioning conventional technology plant 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 Bundle

Of hollow fiber (making sufficient filtration area) is

BIOFLOCS submerged in the bioreactor

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


Backwash is regularly applied to prevent clogging (fouling) of hollow fiber 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:

5-6 log bacteria 2-3 log viruses 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



12


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.
