Low cost adsorbents for the removal of organic pollutants
Water treatment by adsorption using low cost adsorbent is a demanding area as it has double benefits i.e. water treatment and waste management. As discussed in this article various waste products have been converted into low cost adsorbents and used for water treatment. The reported data is very interesting and growing interest in water treatment.
In this article, the technical feasibility of various low-cost adsorbents for heavy metal removal from contaminated water has been reviewed. Instead of using commercial activated carbon, researchers have worked on inexpensive materials, such as chitosan, zeolites, and other adsorbents, which have high adsorption capacity and are locally available.
Low-cost adsorbents for waste and wastewater treatment: a
The recent research interest in low-cost alternatives to activated carbon for waste and wastewater treatment is reviewed. An examination of the selection criteria and activation methods for the preparation of active carbon is followed by a critical assessment of low-cost adsorbents prepared from carbonaceous industrial wastes, agricultural by-products and mineral-derived sources.
Rice husk, which is a relatively abundant and inexpensive material, is currently being investigated as an adsorbent for the removal of various pollutants from water and wastewaters. Various pollutants, such as dyes, phenols, organic compounds, pesticides, inorganic anions, and heavy metals can be removed very effectively with rice husk as an adsorbent.
New Generation Adsorbents for Water Treatment | Chemical
Design and cost analysis of batch adsorber systems for removal of dyes from contaminated groundwater using natural low-cost adsorbents. International Journal of Industrial Chemistry 2025, 263 DOI: 10.1007/s40090-020-00205-1. Xin Xiao, Yihui Wang, Bowen Cui, Xiaobo Zhang, Dongen Zhang, Xingyou Xu.
For this scope, low-cost sorbents have been divided into the following groups according to Ali et al. : (i) Agricultural and household by-products, (ii) industrial by-products, (iii) sludge, (iv) sea materials, (v) soil and ore materials and (vi) novel low-cost adsorbents. To the best of our knowledge, no study that deepening in a systematic
Heavy Metal Removal from Wastewater Using Low Cost Adsorbents
Heavy Metal Removal from Wastewater Using Low Cost Adsorbents These adsorbent includes materials of natural origin like zeolites, clay, peat moss and chitin are found to be an effective agent
Modified biochar, which can be a low-cost and efficient material, is urgently required for Cd-polluted water and soil remediation. Herein, poplar bark (SB) and poplar sawdust (MB) were used as raw materials to prepare modified biochar, which is rich in N- and S- containing groups, i.e., TSBC-600 and TMBC-600, using a co-pyrolysis method
Agricultural Wastes as Low Cost Adsorbents for Water Treatment
Agricultural Wastes as Low Cost Adsorbents for Water Treatment. Pp. 382-412 (31) Ali Ahmadpour, Tahereh Rohani Bastami and Samira Hozhabr Araghi. Abstract. In this chapter, we have reviewed the results of different studies on the removal of aquatic pollutants especially heavy metals and organics by various biosorbents.
Use of waste materials as low-cost adsorbents is attractive due to their contribution in the reduction of costs for waste disposal, therefore contributing to environmental protection. This e-book explores knowledge on recent developments in adsorbents synthesis and their use in water pollution control.

- Can a pH control be used in a drinking water treatment plant?
- This work presents a modelling and a simulation of a pH control for process management in a drinking water treatment plant. A range of historical data, or knowledge base, was used to define the behavior of each input and disturbances of the process, using the MATLAB/Simulink software.
- Is pH a nonlinear problem in water treatment plants?
- In an acidic solution, the pH value is less than 7. The control of a pH neutralization is one of the major problem in water treatment plants, particularly due to its highly nonlinear characteristics [ 2 ]. In the last years, many researchers have studied pH control strategies and methods to resolve or minimize this strong nonlinearity [ 2 ].
- Can pH control modelling be used in a real water treatment plant?
- The present pH control modelling has been simulated and compared to some experimental tests, thus contributing to achieve and identify operational scenarios in a real water treatment plant.
- Does pH affect wastewater treatment cost?
- A study by Alwan (2008) showed that pH adjustment in industrial wastewater treatment plants in uences the treatment e ciency, which leads to an increase in wastewater treatment cost. ... ... Therefore, in full-scale systems, OMWW can be used directly, which will minimize costs during treatment.
