Using electrochemical techniques, such as electrocoagulation,

Electro-flotation and electro-oxidation in organic food treatment

Wastewater. Technical feasibility of various industrial wastewater treatment, such as electroplating wastewater [10]; drink

Water [1 1], [12] oil plant wastewater treatment and municipal sewage [13].

Heavy metal wastewater [14] and [15] nitrite in bin laden wastewater; Defluorination

[16][ 17], arsenic removal; Textile dye [d], garbage

( 19); Restaurant leachate wastewater [20], laundry wastewater

(2 1), surfactant (22); Agricultural industrial wastewater (23), etc.

Established.

Electrochemical coagulation of pulp and papermaking wastewater has been

Technical feasibility. From literature

The conclusion of the experiment is: complete control function

A lot of waste water, etc. )

This is economically feasible. So consider calling.

There are many treatments available.

Technology.

Lignin is completely removed during pulping.

In wood/bagasse, the subsequent reasons are usually not tried.

Economic reasons. Due to the loss of wood fiber and digested chemicals, such tests will affect productivity. High-load wood

Bleaching will increase consumption in addition to bleaching.

Agents and pollution. Therefore, the proportion in practice

Lignin removal is carried out in cooking and bleaching steps.

Optimization. Bleach the organic matter in the wastewater, so dilute it.

Heat and chemical recovery are uneconomical. Therefore, any

The process of strengthening will not escape.

Wastewater treatment and lignin hemicellulose. It's been taken care of.

Safe.

Tamil Nadu Newsprint Co., Ltd. (TNPL Co., Ltd.) is a newsprint and paper company.

The large paper industry is located in Karur, Tamil Nadu, southern India.

State. Lignin and lignin share in kraft pulping process

In the black liquor washing zone, hemicellulose and bagasse are separated from wood. It was burnt down,

Its calorific value and chemical value are recovered in the recovery area.

Plants. Most of the remaining lignin is coming soon.

Filter arrangement from dryer and drum.

This stream, even in quantity (4000m3? ) every day

Lignin and many parts of color

Wastewater flow (56,000m3? One day).

TNPL Co., Ltd. is a company dealing with wastewater flow (mainly high load).

Washing from bagasse, COD:4500mg? ) and a moderate letter of credit.

The rest of the combination, stream (1):1500mgl? Difference of cod
