Why Heat Pumps Don’t Work Well in Cold Environments
08/06/24
“Why don’t heat pumps work well in cold environments?”
Heat pumps depend on using a working fluid to transfer heat from the outside environment to the inside. The working fluid becomes much less efficient when the outdoor temperature hits 5 degrees Celsius. This makes it much more difficult to heat your home effectively. This is Why Heat Pumps Don’t Work Well in Cold Environments.

Why More Water-Efficient Households Can Have Smaller Water Storage Tanks
08/04/24
“Why can more water-efficient households have smaller water storage tanks?”
Water storage tanks’ size is dependent on the amount of water a household consumes. If a household is more water-efficient, it will consume less water and therefore have a smaller water storage tank. This is Why More Water-Efficient Households Can Have Smaller Water Storage Tanks.

Heat Pumps for Water Heating
08/03/24
“How can heat pumps be used for water heating?”
Heating water can take a lot of energy. This makes clean, energy-efficient alternatives all the more necessary in building decarbonization. Heat Pumps fit this bill perfectly, making Heat Pumps for Water Heating a terrific solution.
Why Sludge Fertilizer May Contain PFAS
08/02/24
“Why may sludge fertilizer contain PFAS?”
Sewer Sludge is often reused into fertilizer. However, it may contain harmful PFAS chemicals. This puts people who handle the fertilizer or consumed products grown with it at risk. This is Why Sludge Fertilizer May Contain PFAS.
Secondary Sludge

“What is the sludge resulting from secondary treatment?”
Sewwe sludge is formed during wastewater treatment processes. Secondary Sludge comes from the secondary biological treatment. Primary sludge is composed of both organic and inorganic material while secondary sludge is mostly organic.

“What is the sludge that comes out from primary processes?”
Wastewater treatment processes create sewer sludge. The sludge that comes from the first treatment systems (such as sedimentation and chemical precipitation) is called Primary Sludge.

Nitrogen Water Pollution Remediation
07/27/24
“Why is it bad for water to have too much nitrogen?”
Nitrogen is one of the key ingredients for plant and animal life. However, algae can grow excessively when there’s too much nitrogen in a body of water. This Algae will then suck up the oxygen present in water, block sunlight, and even release toxins. This leads to mass-depth in the bodies of water. Nitrogen Water Pollution is serious and needs to be considered in industrialized developments.

“Why is it bad for water to have too much phosphorus?”
Phosphorus is one of the key ingredients for plant and animal life. However, algae can grow excessively when there’s too much phosphorus in a body of water. This Algae will then suck up the oxygen present in water, block sunlight, and even release toxins. This leads to mass-depth in the bodies of water. Phosphorus Water Pollution is serious and needs to taken into account in industrialized developments.

Effluent
07/25/24
“What is wastewater that flows into surface waters?”
Wastewater comes in all sorts of forms. However, once it’s discharged into surface waters, it gets labeled as effluent. Effluent may be treated or untreated and typically has regulatory guidelines for handling.
