How would you treat and dispose of waste from the sugar industry?

Treatment of the wastes Pollution load in sugar mills can be reduced with better water and material economy practiced in plant. Recycling will reduce the volume of waste to great extent. e.g. volume of mill house waste can be reduced by recycling the water used for splashing.

How does the sugar industry affect the environment?

Sugar mills produce wastewater, emissions and solid waste that impact the environment. The massive quantities of plant matter and sludge washed from mills decompose in freshwater bodies, absorbing all the available oxygen and leading to massive fish kills.

What is the waste product of sugar industry?

The byproducts of sugarcane and sugarbeets that are generated during the industrial processing include sugarcane bagasse, pressmud, molasses, sugar beet mud, and pulp. Generation of sugar industrial wastes/sludges is presented in Fig.

What is the effect of waste from sugar mill on receiving streams?

The sugar mills generate effluent which makes environmental problems related to water and land pollution. The wastewater generated from sugar mills infiltrate into subsoil and leaches into ground water forming contaminated pool which disturb the groundwater quality by changing its chemical composition property [7].

Which type of treatment methods are used for municipal and industrial wastewaters Mcq?

Which type of treatment methods are used for municipal and industrial wastewaters? Clarification: Slow Rate (SR) systems are the predominant form of land treatment for municipal and industrial waste-water.

What is cod range of combined waste in sugar mill industry?

From the initial investigation, it was observed that the COD of untreated effluents was 3,682 mg/l and can be reduced up to 300 mg/l, respectively. Devi et al. (2008) observed COD 22,000 mg/l on coffee processing waste water.

How does sugar affect the economy?

The American sugar industry has a significant impact on the nation’s economy. The industry creates 142,000 direct and indirect jobs in 22 states, and contributes $20 billion in positive economic activity each year.

How does sugar cane farming affect the environment?

When farming techniques harm the Great Barrier Reef. Sugar cane is the major agricultural crop grown within the Reef’s catchments. About 3,000 farms sprawl over 360,000 hectares, some of them dating back more than 100 years. Fertilisers are one of the major sources of nutrients entering the Reef.

What type of industry is sugar industry?

agro-based industry
In India, Sugar industry is the second largest agro-based industry and it contributes significantly to the socio economic development of the nation. Indian sugar industry is also a major sector to create employment probably 7.5 per cent in Indian economy.

How sugar is produced in industry?

Sugar is produced in two principal ways, from beet or cane. In beet production sugar is extracted or leached from sliced sugar beets (cossettes), after which juice is purified through a series of milk of lime and CO2 process steps. The filtered juice is evaporated (thickened) and sugar is crystallized from it.

What is the impact of air pollution on plants?

Effects of air pollution on plants lead to loss of capacity for the plant cell. This is thought to influence the procedure of photosynthesis. Plants get presented to sulphur dioxide through the acid downpour. The quick impacts show themselves as discolouration as an effect of air pollution on leaves.

When the sewage becomes stronger the turbidity of wastewater?

When the sewage becomes stronger, the turbidity of wastewater? Explanation: When the sewage becomes stronger, the milkiness in water increases and thus, the turbidity increases.

What are the waste products of the sugar industry?

The wastes generated from sugar industry are pressmud, bagasse, bagasse fly ash, sugar cane trash, sugar beet mud, sugar beet pulp, molasses etc. These wastes when mixed with other organic substrates become ideal mixtures for growth of earthworms.

What can be recovered from waste sugarcane?

Wax from the press mud can be extracted and may be recovered as a by-product. The recovered wax can be used in manufacturing of shoe polish and carbon paper. Bagasse is another form of solid waste produced after crushing shredded sugarcane and removing sugarcane juice.

Do earthworms play a role in reusing sugar industry waste?

The final product (vermicompost) produced during the process of vermicomposting is nutrient rich organic fertilizer with plant available nutrients such as nitrogen, potassium, calcium and phosphorus. In the present study an attempt has been made to document the role of earthworms in reuse of sugar industry waste.

How are sugar factories classified on the basis of crushing capacity?

As per COINDS/8/1980-81 of Central Pollution Control Board (CPCB), Sugar factories are classified on the basis of crushing capacity as under: The various steps involved for the production of Sugar are as follows: 1. Procurement of Sugarcane. 2. Milling of Sugarcane. 3. Juice Preparation. 4 Juice Concentration. 5.
