Chromium (Cr) exists in aqueous solution as trivalent (Cr3+) and hexavalent (Cr6+) forms. Cr3+ is an essential trace element while Cr6+ is a dangerous and carcinogenic element, which is of great concern globally due to its extensive applications in various industrial processes such as textiles, manufacturing of inks, dyes, paints, and pigments, electroplating, stainless steel, leather, tanning, and wood preservation, among others. Cr3+ in wastewater can be transformed into Cr6+ when it enters the environment. Therefore, research on Cr remediation from water has attracted much attention recently. A number of methods such as adsorption, electrochemical treatment, physico-chemical methods, biological removal, and membrane filtration have been devised for efficient Cr removal from water. This review comprehensively demonstrated the Cr removal technologies in the literature to date. The advantages and disadvantages of Cr removal methods were also described. Future research directions are suggested and provide the application of adsorbents for Cr removal from waters.

Air bersih yang langka di perumahan Valencia Muaro Jambi yang masih dihadapi masyarakat, oleh sebab itu peneliti bertujuan untuk membantu masyarakat perumahan valensia muaro jambi untuk mendapatkan air bersih menggunakan Lapisan Multi Media-Filter Sabut Pinang (LMM-FSP). LMM-FSP merupakan suatu metoda pengolahan air dengan memanfaatkan tanah sebagai media utama yang dibentuk seperti balok bata dan disusun secara selang-seling diantara zeolit. Sistem LMM-FSP terbuat dari galon bekas dicuci bersih tinggi 40 cm berdiameter 28 cm, berisikan blok bata (12x7x4) cm campuran tanah vulkanik, arang, sabut pinang, serbuk besi (70 :10 :10: 5)%, lapisan permiable digunakan zeolit (1-3 mm). Sampel berasal dari sumur warga perumahan valencia, muaro jambi kota jambi. Penelitian dilakukan dengan variasi massa sabut pinang, laju alir 5, 10, 15, 20 mL/menit dan dua cara yaitu aerasi dan non aerasi, diperoleh efisiensi proses aerasi laju alir 5 ml/menit yang paling baik untuk menurunkan kadar pH; Bau; Nitrit; Nitrat; kekeruhan; Mn; Fe pada aerasi yaitu pH 7,5 ; Tidak Berbau; Nitrit 60,30 %, Nitrat 59,33%, Mn 70,10 %, Fe 73,20% dan pada non aerasi pH 7,3 ; Tidak Berbau, Nitrit 50,82%, Nitrat 48,37% Mn 60,91%, Fe 61,20 % Dari semua nilai efisiensi penurunan parameter sudah bisa dikatakan menuhi untuk syarat air bersih[1].

“…According to the statement of DOE, more than 50% of Bangladesh's existing export-oriented industries have established ETP plants and the rest of the industries have not till now. 8 On the other hand, the smaller industries, including local market-oriented industries, do not afford to install a proper ETP plant. That is why any of those factories directly discharge the effluents to the water body.…”

The textile and tannery industry in Bangladesh is liable for polluting the soil and water body owing to the discharge of untreated effluents. They use enormous amounts of water, chemicals, and colorants for processing textile and leather products and release a complex mixture of organic and inorganic pollutants and metal contents, which negatively impact the environment. The main objective of this research was to study the deleterious impact of untreated textile and leather effluents on the environment in Bangladesh. For this purpose, textile and leather effluents were collected from industries during discharging after processing. Parameters, such as BOD, COD, pH, TDS, TSS, TH, Turbidity, conductivity, alkalinity, Dissolved Fe, metal contents, etc., were tested to determine the characteristics of the effluents. Moreover, the impact of these effluents on tree plants as well as on fishes was observed over 24 days. The results showed that the effluents contain extremely high values of BOD, COD, TDS, TSS, hardness, conductivity, alkalinity, silica from the recommended discharge limit. It was also observed that leather effluents cause a more harmful effect on the survival of fishes and trees due to the presence of high metal contents than textile effluents. The findings will help address this alarming situation in the ecosystem of Bangladesh and recommend immediate action to save the ecosystem from untreated discharges of industrial effluents.
