Both the Pharmacopoeia and international pharmaceutical administrations have strict regulations on pharmaceutical water use, and there are corresponding mandatory standards for the discharge of water pollutants in the pharmaceutical industry. Therefore, the selection of water needs to fully consider the specific application areas.
Pharmaceutical wastewater treatment is a major problem in the field of environmental protection. If it is not treated or treated and does not meet the discharge standards, it will cause serious harm if it enters the environment directly. The content of difficult metals such as heavy metals in pharmaceutical wastewater is high, and most of them have strong toxicity and carcinogenic, teratogenic and mutagenic effects. After these refractory pollutants are discharged into water bodies, they are accumulated and enriched. Entering the human body produces toxicity and ultimately destroys the balance of the entire ecosystem. For the six major industrial water pollutants such as fermentation pharmaceuticals, chemical synthesis pharmaceuticals, extractive pharmaceuticals, traditional Chinese medicines, bioengineering pharmaceuticals, and mixed preparation pharmaceuticals, the introduction of relatively strict national mandatory standards (GB21903~) GB21908), need to invest in ensuring the discharge of pollutants.
The stability test is a project that needs to be investigated during the whole life cycle of drug and preparation development and production. In this process, a constant temperature and humidity chamber is required to provide stable environmental conditions. In the traditional humidity regulation control process, a large amount of water is needed, so a considerable amount of waste water is generated, and the content of impurities such as heavy metals is higher than that of raw water or purified water, and it is necessary to undergo subsequent treatment before discharging the pharmaceutical according to law. Factory area.
Although it does not seem to be a large proportion compared to the amount of wastewater produced in the production process, it is an important part of system optimization and industrial improvement. If the optimization is not in place, it will increase the difficulty of the treatment process before discharge, so that the possibility that the water does not meet the discharge standard will increase, and the pollution control cost will increase.
If the new humidity control mode is adopted and the wastewater discharge caused by the humidity control system is reduced, the pressure of wastewater treatment in the later stage can be largely relieved.
Memmert constant temperature and humidity chamber adopts environmentally-friendly humidity control technology, clean and humidify, high degree of automation, low operating cost, stable performance, long-lasting and reliable to maintain stable humidity:
Resistive heating, compared with electrode heating, the humidification system is sensitive and the control accuracy is improved;
The humidified water source uses distilled water or purified water, and does not require raw water such as drinking water, and does not need to be purified;
Dehumidification and no waste water discharge, no need to prepare the waste water receiving system or the sewer pipe and other plumbing construction, does not damage the laboratory environment layout, and has strong compatibility, which is conducive to laboratory function conversion.
There is no correlation between the subsequent wastewater treatment and the discharge discharge inspection, which not only reduces the environmental pressure of the operation of the unit, but also reduces the burden on the overall emission verification, which is conducive to the achievement of the overall wastewater compliance target.
Humidification water consumption, HPP1400 and other models under 25 ° C / 60% RH conditions, the daily humidification water consumption is only about 30 ml.
The laboratory has no floor drain and no damage to the laboratory layout.

Single Packed Yellow Waxy Corn Cob
For the most common waxy and sweet corn on the market, waxy corn has a higher nutrient content than regular corn, containing 70-75% starch (and almost all straight-chain starch), more than 10% protein, 4-5% fat and 2% multivitamins, with more grains, VA, VB1 and VB2 in protein than rice, with the highest fat and VB2 content. Yellow maize also contains carotenoids, such as rice and wheat. The molecular weight of waxy maize starch is more than 10 times smaller than that of ordinary maize, and the starch makes glutinous rice sticky and soft, softer than ordinary hard maize. It is more than 20% more digestible to eat than regular maize and it is suitable for people with less than perfect teeth. At the same time, it is not suitable for diabetics because of the very high content of straight-chain starch (a polysaccharide).
Waxy maize is also known as sticky maize. The grain has coarse, waxy endosperm, similar to shiny, glassy (clear) grains such as hard and dent maize. Its chemical and physical characteristics are controlled by a recessive gene, which is located on chromosome 9. 100% of the starch in the endosperm is straight-chain starch.
