Q:Can the dirty water be filtered out to drink?

Q:How to make a small aquarium filter?
Homemade small fish tank filter:15W pump, flow per hour 800L, so with the 1L loaded pulse bottle, 600ML will overflow.1. now a few small ripple bottle, increase water flow, prevent water small overflow, of course if you pump power is relatively small, but also can not drill.
Q:What is a vacuum filter?
4. ray filterTake out some unnecessary lightAccording to installation method:Oil suction filterOil return filterPipe filterDivided according to performance:Pipe filterDouble drum filterHigh pressure filter
Q:What filters are used in the wells in the rural courtyard?
Rural own wells will generally be self purification, if not particularly muddy, you can not filter. Drinking ground water is beneficial to human health.
Q:Can the water filtered by the filter be drunk directly?
Can the water filtered by the filter be drunk directly?Can drink directly! The filter is to pump water into the container where the filter is placed
Q:How to make filtersOur school requires a filter to clean out the dirty waterI don't know what to do. Please consult me ~!
Find a plastic box and open itThen under the "bottom" uniform gash. Hole can not be too wide (that way, water is too easy to leak down hole) not too narrow (in that case, the water is not easy to drain down), inside the box, some filter cotton on top (if not using space cotton will do it) and have a certain thickness. In addition, conditions permitting, you can also put some activated carbon in the middle of the filter, so better.A hole is placed at the side of the box close to the opening, and a plastic tube is drawn in (for water injection into the box). The other end of the plastic pipe is connected to the pump
Q:What is the difference between a filter and a water purifier?
The second question, trace elements, in addition to drinking water, eating will also have ah, little impact on the body. If the trace element is used, the pollutant is also drunk into the body
Q:How about the water circulation in the air purifier?
The humidifying function leads to the mildew and moisture regain of the activated carbon filter screen.Instead, it affects the overall cleansing effect.
Q:Does anyone know why the water purifier uses the pre filter system?
2, the water purifier "pre filtration system" function is: effectively remove water rust, sand, colloid, and adsorption of water, chlorine, smell, color, pesticides and other chemicals. Pre filter: usually installed in the water after the water inlet pipe, is the first whole house water rough filtration equipment, can sediment, rust, large particles filtered tap water, can also protect the stable water pressure, water purification equipment connected in the back.Therefore, the water purifier is very necessary to use the pre filter system.Tips: popularize the basic knowledge of water purifier;1, water purifier, also known as water purifier, water filter, according to the use of water requirements for water depth filtration, purification treatment of water treatment equipment. The water purifier is usually used as a small filter for household use. The core of the technology is the filter film in the filter core device, and the main technology comes from two kinds of ultrafiltration membrane and RO reverse osmosis membrane. The types of water purifier are: ultra filter, pure water machine and pipe machine.
Q:Why do filters become muddy when filters are used in fish tanks?
To make the water in the tank clear, not cloudy, the following conditions are required:1, the most important thing is to have a functioning ecological filtration system that includes mechanical filtration and biofiltration. Usually the only mechanical filtration to remove solid dirt, and soluble in water, there are a lot, such as organic matter such as protein is not filtered, completed only by biological filtration system to.Water in fish tanks is contaminated by fish droppings, food scraps, and rotting leaves of water plants. In people's imagination, the visible suspension of water is filtered out to keep the water clear and transparent, but it is only the primary function of filtration, which we usually call mechanical filtration. Modern ornamental fish tanks should be mechanically filtered and biologically filtered, and sometimes require physical filtration. Among them, biological filtration is of particular importance. Biological filtration means that the harmful substances dissolved in water can be broken down or converted into harmless substances through bacteria attached to the filter medium, which is the most important filtration function. Physical filtration is the use of certain material specific adsorption functions (such as activated carbon) to purify the water. Physical filtration is used only in exceptional circumstances for short periods of time, such as removal of residual chemicals in water.
