A Comparison Of Applications Of Chemical And Biological Water Treatment Plants
There
are some key differences in the application of a chemical and biological water treatment
plant. Creating a method that meets local guidelines as regards
wastewater disposal poses unique challenges to every industry. Sufficient
treatment is necessary for the prevention of the contamination of receiving
waters yet overtreatment is truly costly. It’s crucial to note that whenever
industries dispose of wastewater, the goal isn’t to produce drinkable water,
but instead water that won’t ruin the environment. Depending on the industry,
chemical, biological, or combination plants for treating water could be the
most effective option.
Chemical treatment plants
Primarily,
these plants are used by the electronics and metal and steel industry, as well
as other varying industries that work with organic chemicals. The pollutants
that these plants target are metallic matter and other varying objects that
alter wastewater’s pH level . Depending on used chemicals, efficiency level has
a large range. As it is a metallic matter that’s being targeted, the efficiency
of treatment is usually around 90% to 95%.
Benefits of chemical plants
The
benefits of using the services of chemical plants are that they demand much
less space than their biological counterparts. Also, the initial plant’s installation,
as well as operation, is relative quite easy. Consequently, it doesn’t require
being professionally managed by any third party. The chemicals that are usually
used in treating water by these plants include aluminium hydroxide, sulfuric
acid, sodium hydroxide, and polymer coagulant. You will discover that most
cities feature a chemical water treatment plant in Australia.
Biological treatment plants
Primarily,
these are used by processing-related industries. This comprises the
textile/dying industry, food processing industry, domestic wastewater
municipalities, leather/fur industry, as well as the paper industry. The
pollutants that are targeted by biological treatment plants are highly polluted
organic matters. This comprises inorganic matter, total nitrogen, organics,
suspended solids, as well as total phosphorus. Biological plants treat mostly
organic pollutants when they are contained in wastewater.
Benefits of biological treatment
plants
There
is a wide range of varying benefits that accrue from the utilisation of a
biological treatment plant. The most notable one among such benefits is a truly
high treatment efficiency. In comparison to chemical treatment plants,
biological treatment plants are a lot more effective across the board. Also,
varying phases of chemical treatment can be eventually included, eliminated, or
even altered depending on the property and kind of wastewater that is to be
treated. This high level of flexibility that is exhibited by biological plants
makes it quite easy for local corporations as well as municipalities to have
their treatment plants modified so they can generate the cleanest wastewater
that can be generated. Also, you will find lots of these plants in many cities
around the world. It all boils down to what suits your wastewater treatment
needs and preferences.
Irrespective
of the kind of water treatment plant or process that is used, there are typically between
4 and 6 stages of treatment which, the water will pass through before it
finally gets released. Even though these stages will be different depending on
treatment effectiveness goals and type of plant, every single stage provides a
unique capability that is quite crucial to the general treatment process.
